Today’s Astronomical Events – May 18th, 2015

2015-05-18 New Moon

New Moon occurs every month when the Moon passes between the Earth and the Sun. This graphic shows the positions of the Moon, Earth and the other planets in their orbits. From Earth’s vantage point, Mars is behind the Sun and Mercury will also soon be invisible. Venus, however, still has some way to go and continues to be easily visible in the early evening sky after sunset.
